Limbo’s secret level actually requires completing the game first and collecting its trophy eggs. Selecting “Load Chapter” from the main menu, scroll across to Chapter 26 . Turn around, go down the ladder and head into the dark tunnel to the right. Traveling a little deeper will bring you to a lit-up field and beyond this area is either a large impassable door or an open entrance, depending on whether or not you collected every trophy egg.

Mentioning that makes me wanna play through this all again... I love how you had to navigate exclusively by sound- And that it was DOABLE. The sound balancing has to be perfect for that. Well done, devs. :P

The 'five deaths or less' achievement gets easy when you get addicted to beating the game, and just play it over... And over... And over... I've sunk a lot of time into this game. lol
